Modeling and Design Tool for Bio-Based Construction Products

As bio-based composites see increased use in protective design more robust material data sets and alternative analysis tools are needed. Improved material characterization and the capability to evaluate close-in effects will enable engineers to evaluate a broader set of design configurations and loading conditions. Three technical objectives are proposed: comprehensively characterize the ballistic response of wood, initiate development of a high-fidelity analytical capability for wood, and extend/validate the analytical capabilities of the Bio-Composite Blast Load Analysis Software Tool (BCBLAST), a fast-running tool capable of assessing the response of bio-based composites to blast and ballistic loading. To this end a materials test program is proposed. Results from this test program will be used to develop a wood constitutive model for use in finite element analyses. In parallel, a comprehensive CLT ballistic test program is proposed along with improvements to the Phase I BCBLAST tool. Expected outcomes include: dynamic characterization test data, expanded ballistic impact datasets and improved penetration equations, a proof-of-concept wood constitutive model, and an updated version of BCBLAST. These outcomes provide an advancement of the state-of-knowledge with respect to wood material behavior and improved design tools to advance the deployment of wood materials in protective design settings.

The goal of phase II is to continue the R&D efforts initiated in Phase I. Funding is based on the results achieved in Phase I and the scientific and technical merit and commercial potential of the project proposed in Phase II. STTRs are completed in conjunction with a research institution.
